Original application med September 17, 1923, Serial No. 863,052. Divided and tlm application tied rem-nary e, im.

This invention lis concerned with a car' bonator particularly adaptedto be employed in connection with dispensing apparatus of the character shown and described in my 6 oo-pending application, Serial No. 663,052 filed under date of September 17, 1923, of which this application is a division.

The object of this invention is brnadl to v provide an improved carbonator whic is l0 particularly adapted to, diffuse a carbonat# ing gas through a beverage that is to be dis;

Fig. 1.

n the drawing, my im roved carbonator is designated generally y the reference character 11. AThe carbonator 11 is adapted to be used in connection with a carbonio gas.

tank (not shownz of usual construction iiioluding a valve` or regulatin the ressure of the gas which flows from t e tan The carbonio gas tank supplies a carbonating agent to the carbonator which, in turn, supplies a carbonated liquid to a draught arm orjfaucet (not shown). Asthe carbonator is the subject-matter of this application, no description 'of the carbonio gas tank or the draught arm need be given. However, the carbonio gas is sup lied to the carbonator by way of a flexible tu e 14 which `fcommunioates with the aforementioned carbonic gas tank. The as is diiused through y of beverage e'ld' in the carbonator and t e beverage after being properly carbonated is fed under the desired ressure to the draught arm. In ractioe, t e flow `of carbonio gas to the car onator is controlled 46 by the aforementioned regulating valve of the carbonio gas tank and .to some extentby a valve 17 carried by a head 18 rigidly secured tothe upper end wall of a substantially cylindrical drum`19 which, to-

5 0 ther'with a base 20 and a cover plate 21,

orms a chamber 22 adapted to old the beverage which is to be carbonated and dispensed. A chamber 23 located in the lower end of the carbonator 11 is separated from apertured boss form the. chamber 22 vby a partition or wall 24 55"A which preferably comprises af rous arti vioial stone 25 manufactured of siliceous ma terial. 'As shown in Fig. 1, the artiiioal stone 25 vis preferably disposed between a plurality of perforate plates 26 and 27, the 00 perforate late V26 being held in placevby a ring 28Y w ich, together with the perforate plate 27 and the cover plate 21, is ri'odly secured to the base 20 by a plurality of lts 29. The partition or wall 24 permits cara bonio gas to pass from the chamber 23` into the chamber 22, the carbonio gas being supplied tothe chamber 23 by a ipe 3() which communicates at a'll times wit the flexible tube 14 and which also communicates at all 7 times with the chamber 23 through the medium of a T-ttin l31 threaded into an` upon the cover plate 21. The T-iitting is`bored to receive a small section of pipe 32 which rejects into the 'l5 i chamber 23 and which is a 'apted to receive the gas flowing from the pipe 30 and to discharge this gas iny close. proximity to the partition or wall 24. A second bore, indicated by the reference character 33, in the 80 T-fttin 31 communicates with' a pipe 34 thread into the T-tting. The bore 33,

together with the pi 34 and a valve 35,

povide meanswhere y the chamber 23 can drained of any beverage-which may seep a5 through the wall 24. The chamber 22 ma be drained through a pipe 36 which is threa ed into an openln 36 in the base 20. A

valve 37 is provid for controlling the ow of beverage through the pi 36. 90 Depending from the hea 18 and disposed substantially central. of the cylindrical drum 19 is a pipe '38. The pi 38 provides means whereby the carbonate beve mayilow .from the oarbonatorll to the taught arm` 06 by `way of a tube 39. -A valve carried by the head 18 is adapted to control the iow of beverage fromthe pipe 38 to the ipe 39.

As hereinbefore set'forth, the exible tube 14 is at all times in communication with the -101! pipe 30 (Fig. 2 This construction permite' the beverage to be subjected at all times to the carbonating inuence of the gas llowing from the carbonio gas tank, the pressure of the gas being controlled by the -valve of the gas tank. The glas whi enters the carbonator by way of t e flexible tube 14 and the pipeBOmust, of course, pas

gingios' through the orous stone 25 if it is to carbonate the everage. However, carbonic s may be admitted directly to the chamggr 22 from the fiexible tube 14 by way of a bore 18'* formed in the head 18, the valve 17 servin to control the flow of gas from the flexible tube 14 to the bore 18f. By this means the pressure is balanced, and carbonization will be checked as the beverage is drawn off.

As best shown in Fig. 2, the head 18 is provided with a filling o ening 41 and a vent opening 42, screw threa ed plugs 43 and 44 being provided for the openings 41 and 42 res ectively. The plu s 43 and 44 are wit drawn, of course, rom the openings 41 and 42 when the chamber' 22 is to receive a supply of beverage. I prefer to rovide a gauge 45 having` a sight glass 46 w ich indicates, at any time, the amount of beverage contained -in the chamber 22.

In the operation of the above described carbonator, the beverage to be dispensed is introduced to the chamber 22 through the filling opening 41, the plufrs 43 and 44 having been withdrawn from tlie filling opening 41 and the vent opening 42 in the head 18. The regulating valve of the carbonio gas tank, the valve 17 and the valve 40 are closed durin the filling operation, the regulating valve eing opened directly after the plugs 43 and 44 have been replaced in the openchamber 23, the

ings 41 and 42 respectively after a desired amount of beverage has been supplied to the carbonator. It is preferable that the beverage does not completely fill the chamber 22 as it is advantageous to leave a space at the top 'of the chamber into which space car-- bonio gas may be later introduced by way of the valve 17 and bore 18, to balance the pressure. The initial adjustment of theregulating valv'e of the carbonio gas tank,

after the filling operation has been comsleted, permits the carbonio gas to flow uner comparatively high pressure throu h the flexible tube 14 and the pipe 30 to t e gas then passing through the porous artificial stone 25 into the chamber 22 where it diffuses through the beverage contained in the chamber. The beverage becomes thoroughly saturated with gas four lor five minutes after the initial adjustment of the regulating valve and after such saturation the regulating valve is again adjusted to reduce the pressure of the gas flowing to the carbonator. The valves 17 and 40 are then opened and the carbonator vis ready for use. By making the entire partition between the chambers 22 and 23 of porous stone, the gas passing through the stone is diffused therethrough,`so that when it reaches the chamber 22 it is applied to the liquid over a large area, thus providing for rapid carbonization.

Iam aware that changes in the form, constructionand arrangement of arts may be made Without departing from t espirit and without sacrificing the advantages of the invention and I reserve the right to make all such changes as fairly fall within the scope of the following claims.

I claim:

A carbonator comprising a drum having the bottom end thereof open, a support having a concave base for supporting said drum, a porous stone interposed between said drum and said base for forming an upper and lower chamber, a head mounted on the top of said drum, a gas inlet valve communicating with the top of the drum for the entrance of gas in the drum, means connecting said inlet valve and said lower chamber to allow gas to enter said lower chamber, a plu threadedly mounted in said head to allow t e upper chamber to be filled with fluid, a fluid outlet valve, and means connected to said outlet valve and extendi to the bottom of the upper chamber for a lowin the fluid to be withdrawn therefrom.

2. carbonator comprising a drum having the bot-tom end thereof open, a support having a concave base for supporting said drum, a porous stone inter osed between said drum and said base for orming an upper and lower chamber, a head mounted on the top of said drum, a gas inlet valve communicatin with the top of the drum for entrance o gas in the drum, means connecting said inlet valve and said lower chamber to allow gas to enter said lower chamber,-a plug threadedly mounted in said head to allow the upper chamber to be filled with fluid, a fiui outlet valve, means connected to said outlet valve and extendin to the bottom of the up er chamber for a lowing the fluid to be witl'idrawn therefrom means for draining the upper chamber, and draining the lower chamber.
